Yakakurumbira fekitori yemhando yepamusoro Poly (1-vinylpyrrolidone-co-vinyl acetate)/VP/VA CAS:25086-89-9
Kutanga uye pamberi pezvese, iyi copolymer ine yakanakisa yekugadzira firimu zvinhu.Inogona kuumba firimu rakajeka nekunamatira kwakanakisisa uye kusimba.Izvi zvinoita kuti ive yakanaka kune machira uye zvinonamira zvinoshandiswa mumhando dzakasiyana siyana zvinosanganisira pendi, varnish uye varnish.
Pamusoro pezvo, vinylpyrrolidone-vinyl acetate copolymers inoratidza kunyungudika kwakanyanya mumvura uye kwakasiyana-siyana organic solvents.Solubility iyi inobvumira kuti ishandiswe seyakakora mumiriri mune akasiyana magadzirirwo, kusanganisira ega ega zvigadzirwa senge bvudzi gels, sprays uye lotions.Iyo yakanakisa adhesive properties yeiyi copolymer inoitawo kuti ive chinhu chakakosha mukugadzirwa kwemapiritsi uye capsules yeindasitiri yemishonga.
Uye zvakare, iyo conductivity yevinylpyrrolidone-vinyl acetate copolymers inogona kugadziridzwa zvinoenderana nezvinodiwa chaizvo, ichiita kuti ive yakakodzera kune zvemagetsi uye conductive coating application.Kuenderana kwayo neakasiyana ma substrates akadai sesimbi, mapurasitiki uye machira anowedzera kune zvakasiyana-siyana uye kushandiswa kwayo.
Pamusoro pezvo, vinylpyrrolidone-vinyl acetate copolymers yakagadzikana nemhepo uye inoshingirira kune UV mwaranzi, ichiva nechokwadi chekugara uye kushanda kwenguva refu kwekushandisa kunze.Izvi zvinoita kuti ive sarudzo yakanakisa yekudzivirira machira pazvivakwa, mota nemidziyo yemagetsi.
Muchidimbu, vinylpyrrolidone-vinyl acetate copolymers ine yakanakisa firimu-inogadzira zvimiro, solubility, magetsi conductivity, uye kugadzikana kwekupisa, ichipa mikana yakawanda yemaindasitiri akasiyana.Zvishandiso zvaro zvinotangira kumapeji uye zvinonamira kune zvigadzirwa zvekuchengeta zvega uye zvemagetsi.Isu tine chivimbo chekuti vinylpyrrolidone-vinyl acetate copolymers yedu ichasangana uye inodarika zvaunotarisira nemhando yavo yepamusoro uye kuita kunoenderana.
